For some odd reason, whenever I try to make lipsync on TF2 models using "Extract Phonemes" The lips are not changed in any way. The lips do not move with the audio, and yes I have made sure to have the audio clips show their waveforms and that they were selected upon extracting phonemes. I even tried using an HWM model and that didn't work. Can anyone help fix this?

First off, are the sound files you're using .wav files or mp3 files? If .mp3 they can not be used in lipsync. The Lipsync animations are created by the waveforms in the .wav file. Next if you are using .wav files are they 16bit 44.1 k files, if higher, they will not work in SFM Lipsync.

Now, the models themselves, must be hwm models for lipsync. The player models don't have the necessary flexes.
